- Abstract
WinFit software is used to determine using the profile of a single diffraction peak the sizes of coherent scattering domains and microstrains for tungsten powders obtained through plasma chemical synthesis and hydrogen reduction from tungstic acid. It is shown that the use of the (110), (200) or (211) diffraction peaks is the most expedient for the calculations. At the same time, it should be noted that, in the case of significant microstrains, the sizes of coherent scattering domains calculated using the second and the third peaks are underestimated.
